Sorry, I have been trying to find some posts relating to 2 issues I am having.

I have only just got my first rebuild/ restore/ US car. '79 C3. 2 issues, Horns sounding constantly, something not right with horn switch on steering wheel, any pointers please, is there a repair kit you can get? Also idle is very rough. I have vacuum lines disconnected and blocked and one from under the air cleaner that has broken off. It is small diameter and have white plastic joiner snapped off inside. I have searched and searched and cannot find where it goes/ comes from, but seems to have little to no vacuum when you cover with your finger. Does anyone have a diagram of the vacuum plumbing or Emissions systems for stock '79 C3 350? Only had the car a week and sorting the obvious stuff first... Appreciate any help  :huh:

The horn is grounding out.  Do you have the little spring under the horn button?  Could also be the lower horn ring grounding out the column - http://willcoxcorvette.com/product_info.php?products_id=24018

Whereabouts in Sydney are you?

thanks for the replies, both have pointed me in the direction I need to go. Looks like I need to get the steering wheel off to see lower section. BTW, on the link for Jim Shea's he talks of a host website to download images of steering columns etc. Does anyone know the host website?

My location is Western Sydney near St Clair.
